Space photographs of the week: the trail of opportunity and much more



Long and Martian Road: In August 2010, the Marshall Opportunity looked around and made a photo of its tracks on the sand of the Red Planet. This image has beautiful ripples of small dunes created by the wind, similar to those we have here on Earth. The opportunity took many epic shots, like this, as he cruise around Mars for 15 years. Now it's lost for us.

See more dunes: these crescent-shaped sand formations are called Barkhan dunes. From this photograph taken by the HiRISE Mars Reconnaissance Orbiter, scientists can say that the prevailing winds blow from east to west. The wind pushes fine grains of sand onto the slopes, creating ripples and making these captivating forms.

Opportunity is lost, but we have not done with Mars yet. Earlier this month, InSight Lander successfully placed a thermal wind and heat shield on its seismometer. NASA's Orchestra Mars Reconnaissance flew over its head and not only noticed the dark solar panels of the landing gear, but also a new shield ̵

Around the ship and the shield are shaded areas that indicate that during landing the dust is undermined when InSight released its retro-launches to slow down. This is an interesting photo that we get when our works spy on our other works. . Like the Earth, these ice planets have seasons, but they cover decades, not months. On Neptune's right, the storm went dark: vortex at a distance of 6800 kilometers jumped up in the upper center, along with white "clouds of the satellite." . Scientists attribute the strange weather on the Uranus to the rotation of the planet, as it is inclined almost the entire side. Uranus is drawn to the Sun with its northern pole during the long summer, and the theory believes that this polar hood occurs as a result of atmospheric flux changes. The Telescope of the European Southern Observatory has photographed a multichannel system called the AS 205. An extremely interesting disc in the lower right corner, which is a binary system. Although we are not at the point where we can see two stars in the disk, the gravity of each of them interacts with another and leaves evidence of their drag and drop drag. According to astronomers, such systems are not unusual; The key issue is that their duality affects the formation of planets. When you have more than one star, the material moves in more complex ways.

Are you stunned by the star? This complicated photograph of the Galaxy Triangle, also known as Messier 33 or M33, uses 54 Hubble views. The actions of scientists determine 25 million stars, scattered here, from left to right, at a distance of approximately 14,500 light years. The M33 is a spiral galaxy similar to our own Milky Way, so astronomers study both of these spiral galaxies as proxies for our own.
